Geographically Diverse Fiber for<br />
Redundant WAN Connectivity<br />
<strong>CIT</strong> maintains a fiber p<strong>at</strong>hway for<br />
d<strong>at</strong>a along the east side of Cayuga Lake<br />
to Syracuse . This year an additional<br />
fiber p<strong>at</strong>h was built up the west side<br />
of the lake to Rochester . The new fiber<br />
p<strong>at</strong>h meets a number of important<br />
needs for the campus, increasing<br />
communic<strong>at</strong>ion capabilities, security<br />
options, <strong>and</strong> connectivity backups .<br />
A spur off the main fiber <strong>at</strong>taches<br />
to the Geneva Research St<strong>at</strong>ion,<br />
providing ten gigabit-per-second d<strong>at</strong>a<br />
connectivity <strong>and</strong> better phone service<br />
to the Geneva campus . This allows<br />
videoconferencing between Geneva<br />
<strong>and</strong> Ithaca <strong>and</strong> also gives researchers<br />
in Geneva access to the Center for<br />
Advanced <strong>Computing</strong> <strong>and</strong> large<br />
d<strong>at</strong>abases on the Ithaca campus . In the<br />
event of a disaster, the Geneva facilities<br />
can now be leveraged as an emergency<br />
staging area for Ithaca comput<strong>at</strong>ional<br />
resources .<br />
At Rochester, there is a backup<br />
Internet2 Research <strong>and</strong> Educ<strong>at</strong>ion<br />
connection th<strong>at</strong> is autom<strong>at</strong>ically<br />
brought up if there is a loss of <strong>Cornell</strong>’s<br />
main Internet2 connection . Internet2<br />
is a high-speed network for higher<br />
educ<strong>at</strong>ion . The Rochester connection<br />
also allows <strong>Cornell</strong> to dynamically form<br />
a ring back to <strong>Cornell</strong>’s equipment<br />
in Syracuse in case of a break in the<br />
fiber connection between Ithaca <strong>and</strong><br />
Syracuse to re-establish our multiple<br />
connections to NYC .<br />

Network Capacity Doubled for<br />
EZ-Backup <strong>and</strong> Other Initi<strong>at</strong>ives<br />
<strong>CIT</strong> lit up an additional 10 gigabitper-second<br />
connection from Ithaca<br />
to Syracuse to New York City . From<br />
the <strong>Cornell</strong> router <strong>at</strong> 32 Avenue of<br />
Americas, it provides high-speed<br />
connectivity to Weill <strong>Cornell</strong> Medical<br />
College, as well as to many other<br />
research institutions around the world .<br />
The 10 Gbps lambda is not a<br />
physical connection, but a particular<br />
wavelength of light used across a<br />
series of Dense Wavelength Division<br />
Multiplexing (DWDM) connections .<br />
EZ-Backup d<strong>at</strong>a is sent across the<br />
connection to a secure secondary<br />
system <strong>at</strong> the Weill <strong>Cornell</strong> Medical<br />
College facility . The connection can<br />
also be used for real-time video<br />
collabor<strong>at</strong>ion between the two<br />
campuses .<br />
Comprehensive Video Streaming<br />
Architecture Emerges as a<br />
Campus-Wide Need<br />
In 2009, <strong>CIT</strong> launched a campus-wide<br />
collabor<strong>at</strong>ive effort to develop video<br />
streaming technology st<strong>and</strong>ards <strong>and</strong><br />
support services for the future .<br />
While the university has been<br />
streaming video for years, the<br />
continuing increase in dem<strong>and</strong><br />
underscores the necessity for a scalable<br />
architecture th<strong>at</strong> accommod<strong>at</strong>es the<br />
variety of video streaming needs across<br />
campus—everything from podcast<br />
quality to the near-broadcast quality<br />
usually needed for distance learning<br />
classes .<br />
The new architecture will define:<br />
▪ A content management system for<br />
c<strong>at</strong>aloging, editing, <strong>and</strong> publishing<br />
audio/video streams .<br />
▪ An audio-video capture system for<br />
producing a range of quality, <strong>and</strong><br />
servicing a variety of venues . For<br />
example, <strong>Cornell</strong> might need some<br />
systems th<strong>at</strong> are fixed in one place,<br />
perhaps in selected classrooms,<br />
<strong>and</strong> some portable systems th<strong>at</strong> are<br />
easily moved .<br />
▪ A media hosting solution for<br />
storing video <strong>and</strong> serving it out in<br />
appropri<strong>at</strong>e form<strong>at</strong>s .<br />
The first step in the process has been<br />
to engage the university community<br />
in a series of discussions held during<br />
the 2009 IT Forum <strong>and</strong> two video<br />
summits hosted by <strong>CIT</strong> <strong>and</strong> <strong>at</strong>tended by<br />
members of <strong>Cornell</strong>‘s Ithaca <strong>and</strong> Weill<br />
<strong>Cornell</strong> Medical College audio-visual<br />
communities .<br />
A variety of needs, concerns,<br />
questions, <strong>and</strong> approaches emerged<br />
along with a straw architecture based<br />
on st<strong>and</strong>ard technologies <strong>and</strong> systems .<br />
The next step is to establish a video<br />
streaming task force to advise <strong>CIT</strong> <strong>and</strong><br />
<strong>Cornell</strong> as the university develops its<br />
comprehensive video streaming plan .
